I reckon that’s being over-generous, tbh.
We don’t know how this GE will pan out.
Scotland’s MP count wasn’t decisive in 2017 or 2015.
2010: ok, Cons were deprived of a majority that they might otherwise have got if, in miracle-land, they’d managed more than just 1 MP in Scotland and won half of them. Whatevs, they still ran the Gov.
Gotta go back to '74 for a proper example, where Scottish MPs made a required contribution to Wilson’s narrow win.
